ZM9101 Liquid Extraction Unit Vocational Training Tools And Equipment Hydrodynamics Laboratory Equipment

Apparatus The apparatus consists of a liquid-liquid extraction glass column mounted on the side of the distillation column.

This last column can be used to recover the solvent for extraction or to be used separately for the distillation process.

This unit can develop and analyze the following topics: Extract

  • Determine the number of transfer units
  • Height of the transfer unit
  • Extraction efficiency
  • Mass balance
  • Calculation of mass transfer coefficient
  • Calculate the number of theoretical stages
  • Concentration trends along the column
  • Practice on a system with 3 partially mixable components:

 

Distillation

  • Recover the solvent used in the extraction
  • Distillation of different mixtures (water/ethanol, water/methanol, methanol/propanol, etc.) with changes in the following operating parameters: – reflux ratio – feed flow rate – reboiler heating power – feed composition
  • flood
